What is Proton VPN?
Proton VPN is a virtual private network client developed by Proton AG, the team behind Proton Mail. It uses strong encryption protocols like WireGuard and OpenVPN to secure your internet connection. The Linux version is built from Proton's official open-source code but is distributed via Flathub, meaning it is not an official Proton app and lacks direct support from the company. It is a mature tool used by millions worldwide to protect online privacy.
This app is ideal for users who need to bypass geo-restrictions, access streaming services, or simply keep their browsing history private from ISPs and advertisers. It suits both casual users wanting basic privacy and power users who need advanced features like Secure Core double-hop connections or Tor integration. If you are coming from Windows, you will find the interface familiar, though the Linux version may lack some of the polished extras found in the official Windows client.
Compared to CyberGhost, Proton VPN offers a stricter no-logs policy and transparent, open-source code. While CyberGhost is proprietary, Proton allows you to verify its security claims. The experience is straightforward: connect to a server, and your traffic is encrypted. It feels less like a bloated suite and more like a focused utility that does one job well without intrusive ads or data collection.
Best for: Privacy-conscious Linux users who want a reliable, open-source VPN with a strict no-logs policy and no data limits on the free plan.

How to install Proton VPN on Linux
flatpak install flathub com.protonvpn.wwwTips for Windows users
If you are moving from CyberGhost, note that Proton VPN does not share configuration files or saved server lists. You will need to log in with your Proton account to access your subscription benefits. The interface is similar, but expect to use the Flathub version, which may have slightly different menu layouts. Your saved passwords and settings from the Windows client will not transfer automatically, so keep your account credentials handy. The core workflow of selecting a server and connecting remains the same.
